The Lying Game is a one-hour scripted drama which follows Emma, a kind-hearted foster kid who can't catch a break. She finds out she has an identical twin sister, Sutton, who - unlike Emma - was adopted by wealthy parents and is seemingly living an ideal life.
After their initial meeting, Sutton talks Emma into stepping into her life for a few days while she pursues a lead on their birth mother. Initially excited to do this favour for her sister, Emma soon learns that Sutton has gone missing and could be in trouble. Now, Emma must decide whether to come clean to Sutton's family and risk her own safety in the hope of uncovering her twin sister's true whereabouts, along with the truth about why they were separated in the first place.
01 - Pilot
In the series premiere, Emma, a kind-hearted foster kid, has recently discovered she has an identical twin sister, Sutton. Unlike Emma, who has bounced from foster home to foster home, Sutton was adopted by wealthy parents, Ted (series star ANDY BUCKLEY) and Kristin Mercer (series star HELEN SLATER), and is seemingly living every teenager's dream life. Both girls are eager to meet each other in person, yet Sutton feels it is better to wait until she tells her adoptive parents what she has discovered. Emma and Sutton agree to continue their separate lives - but when Emma has an unfortunate encounter with her foster family and is forced to flee, the only person she can turn to is Sutton. Upon meeting in person for the first time, Sutton talks Emma into stepping into her life for a few days while she pursues a lead on the identity of their birth mother. Though doubtful that she'll be able to play the part of a rich girl and blend seamlessly into Sutton's life, Emma agrees and enters what once was only a fantasy world to her. But while the twins may look exactly alike, their mannerisms are far from identical: unlike Sutton - who has been standoffish with her family, especially her younger sister, Laurel (series star ALLIE GONINO) - Emma is polite and gracious. Plus, Emma must now play the part of the "it" girl, something she has never been, and though this means built-in friendships with Madeline "Mads" Rybak (series star ALICE GRECZYN) and Charlotte "Char" Chamberlin (series star KRISTEN PROUT), it also means the consequences that come with that title, including a rivalry with Nisha Randall (series star SHARON PIERRE-LOUIS), who seems bent on besting Sutton. To complicate matters further, Emma discovers that Sutton has been keeping some secrets of her own. For example, who exactly is Ethan Whitehorse (series star BLAIR REDFORD), a boy at Sutton's school who always seems to be lurking nearby? Though their plan is going well enough, on the night Sutton and Emma are scheduled to meet again, Sutton fails to appear. Now Emma must decide whether to come clean about her true identity - and risk her own safety in the hopes of uncovering Sutton's whereabouts, along with the truth of the separation - or continue to play the part of the perfect girl and hope her long-lost sister knows what she is doing.
02 - Being Sutton
Since concern for Sutton's safety seems to be occupying Emma's mind, she starts to let pieces of her own personality emerge. Although Emma is worried by her behaviour, it seems her friends and family are enjoying the change in the person they think is Sutton. Wanting to please the father she never had, Emma must learn to ballroom dance for the annual father-daughter dance. Realizing she is in dire need of assistance, Ethan offers to help, in turn risking revealing his and Sutton's secret relationship. Will Emma be able to put aside her worries for Sutton and shine on the dance floor? Or will the night's series of events force her to reveal her true identity? Meanwhile, as the teenagers do anything to keep their secrets, the parents may be lying to keep life-altering secrets of their own.
03 - Double Dibs
After revealing Sutton's real relationship with Ethan, the Mercers insist she invite him over for dinner. Hesitant because of his obvious feelings for Emma, Ethan obliges, only to have the dinner cut short by a disturbing visit from his brother, Dan (recurring guest star TYLER CHRISTOPHER -- Into the West, General Hospital ). As Emma and Ethan struggle to keep order in Arizona, Sutton and Thayer (recurring guest star CHRISTIAN ALEXANDER -- Eastwick ) discover shocking revelations in Los Angeles pertaining to the search for the girls' birth mother. Although the outcome may not turn out to be what Sutton had hoped for, it does lead her to wonder what it is that everyone around her has been hiding all of these years. Will Sutton be able to find the answer about why she and Emma were separated, or will her curiosity put her and her loved ones' lives in danger? Meanwhile, Laurel falls for a new guy in school hoping she will finally emerge from being in Sutton's shadow and have something of her own. Unfortunately, her wishful thinking is cut short when Char calls dibs on the one Laurel did not want to share.

After waking up from a terrifying nightmare, Emma learns that Sutton has been suffering from the exact same dream for years.

It is not until during a nighttime rendezvous with Ethan that Emma remembers pieces of her former life, allowing Sutton to locate the house which Emma shared with their long-lost mother, as well as secrets many around them have tried to hide. Will the house and the new information be the missing piece of the puzzle, or are the superstitions true? Can curiosity kill? Meanwhile, with Ethan facing a lot of trouble, Emma tries to convince Ted that Ethan is innocent. But when she pushes, Emma sees she has hit a nerve with Ted, leading her to believe that he might be hiding something. Although she does not know what, it appears Ted is feeling guilty and knows more than he is willing to share.

Realizing that she must go through with it, Emma is rushed back into the spotlight and finds herself clinging to Ethan for support and comfort. Although both know Sutton wants the relationship kept a secret, the homecoming dance electrifies feelings that have been present from their first meeting. Will Ethan and Emma go behind Sutton's back and finally take the "secret" relationship public? Or, by doing so, will a much anticipated relationship emerge? Meanwhile, Alec Rybak (recurring guest star ADRIAN PASDAR - Heroes ) seems to be increasingly close to catching on to Sutton and Emma's switch.
